Dimethyl carbonate (DMC) is a chemical raw material with low toxicity, excellent environmental performance and a wide range of uses. It is an important organic synthesis intermediate. Its molecular structure contains carbonyl, methyl and methoxy groups. Such functional groups have a variety of reaction properties, and are safe to use, convenient, less polluting, and easy to transport in production. Used in the production of polycarbonate, isocyanate, polyurethane, polycarbonate diol, allyl diethylene glycol carbonate, naphthyl methylcarbamate (carivin), anisole, tetramethyl alcohol Various chemical products such as ammonium, long-chain alkyl carbonate, carbohydrazide, malonate, malondiurethane, diethyl carbonate, triphosgene, furazolidone, methyl carbazate, methyl anilinoformate, etc. Because DMC is non-toxic, it can replace highly toxic phosgene, methyl chloroformate, dimethyl sulfate, etc. as a methylating agent or carbonylation agent to improve the safety of production operations and reduce environmental pollution. As a solvent, DMC can replace freon, trichloroethane, trichloroethylene, benzene, xylene, etc. for paint coatings, cleaning solvents, etc. As a gasoline additive, DMC can increase its octane number and oxygen content, thereby improving its anti-knock properties [1]. In addition, DMC can also be used as an additive for detergents, surfactants and softeners. Due to its wide range of uses, DMC is known as the "new cornerstone" of today's organic synthesis.
